Hi everyone,
I noticed a new option in configuring PaX in the kernel with version
2.6.26. It says:
Prevent various kernel object reference counter overflows
The description says that it "prevents overflowing various (but not all)
kinds of object reference counters." I'm not familiar with this exploit
technique. Does anyone know of any proof of concept code?
